At present sandbox only supports a basic set of features. To help address
this, a recent series added SPI and SPI flash support; this series expands
the coverage further.

Firstly SDL is used to provide LCD and audio support. Sandbox gains its own
LCD driver which can display images, host a command line, etc. The audio
support is basic and needs additional work, but it is a starting point.
SDL also provides a keyboard emulation (using the Chrome OS EC code as a
base).

Secondly a TPM emulation is added. This does not include all features (the
implementation is quite simplistic) but it is enough to do basic secure
boot operations.

Finally, various pieces of useful infrastructure are added, including:

- loading and saving of the emulated SDRAM to permit test runs to carry
over state
- loading and saving of general sandbox state (for example a driver can
save its stage and reload it on the next run)
- support for using bootm to load a kernel
- providing a device tree for use by sandbox
- a means to jump to another U-Boot while preserving state (useful for
test environments which want to run a series of tests with
script-selectable state)

Major functions which still remain without sandbox support are I2C,
networking and USB.

Note:

Much of this series was sent out in November. Due to problems with the
LCD side it was not ready for the last release, although about a dozen
patches from the series were applied. I have rebased and tidied things
up. U-Boot now starts by default without the LCD visible since for
much sandbox testing we don't want the LCD. The Chrome OS EC code has been
updated and tidied up and full keyboard support is now present in the LCD
window.

Changes in v2:
- Add new patch to adjust #ifdef position in cros_ec
- Add new patch to sync with latest Chrome OS EC version
- Add new patches to bring in protocol v3 support
- Rebase to master
- Update series to take account of patches now merges from original series
